Remember also the time when your Lord declared, 'If you are grateful, I will surely bestow more favours on you; but if you are ungrateful, then know that My punishment is severe indeed.'" 7 And Musa said: if ye disbelive, ye and all those who are on the earth - then verily Allah is Self-Sufficient, Praiseworthy. 8 HAVE THE STORIES of those [deniers of the truth] who lived before you never yet come within your ken - [the stories of] the people of Noah, and of [the tribes of] 'Ad and Thamud, and of those who came after them? None knows them [now] save God. There came unto them their apostles with all evidence of the truth - but they covered their mouths with their hands and answered: "Behold, we refuse to regard as true the message with which you [claim to] have been entrusted; and behold, we are in grave doubt, amounting to suspicion, about [the meaning of] your call to us!" 9 ۞ Their messengers said, "Can there be doubt about Allah, Creator of the heavens and earth? He invites you that He may forgive you of your sins, and He delays your death for a specified term." They said, "You are not but men like us who wish to avert us from what our fathers were worshipping. So bring us a clear authority." 10 Their Messengers said to them: "We are no more than human beings like you, but Allah bestows His Grace to whom He wills of His slaves. It is not ours to bring you an authority (proof) except by the Permission of Allah. And in Allah (Alone) let the believers put their trust. 11 And why should we not repose our trust in God when He has shown us our paths of duty to Him? We shall bear with fortitude the hardships you inflict upon us. The trusting place their trust in God." 12
